Congenital Nasal Pyriform Aperture Stenosis Repair: A Case Series and Discussion of Postoperative Care

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare condition related to holoprosencephaly in which bony overgrowth of the medial nasal process of the maxilla narrows the pyriform aperture. CNPAS presents in neonates with signs of upper airway obstruction ranging from mild to severe respiratory distress and failure to thrive. Surgical intervention is indicated after failed conservative measures and generally includes temporary stent placement. We report a series of 3 cases of CNPAS treated surgically, examine postoperative care recommendations in the literature, and present a comprehensive postoperative care regimen with a novel method to maintain stent patency
